  • The purpose of this study was to develop an instrument for assessing the attitude and the knowledge level of elementary school in-service and pre-service teachers' on the modem environmental issues, and to implement it. The results of this study could be summarized as following. First, the instrument for attitude was developed as a Likert-type scale, it was constituted of 30 items through the item-chosen processes to improve the validity and reliability. The Cronbach's Alpha coefficient of the attitude instrument was .899. Second, The instrument for knowledge was developed as a multiple-choice form with 와 distracts, and the final version was constituted of 35 items. The average discrimination, difficulty, and Cronbach's Alpha coefficient of the items were .367, .629, .899, respectively. Third, in-service elementary teachers have been thinking about the modern environmental problems more seriously than pre-service teachers. However, in-service teachers 'knowledge level was lower than pre-service teachers'. Fourth, women have been thinking about the modern environmental problems more seriously than men. However, there was no difference significantly between men and women on knowledge level. Fifth, This process of developing the instrument could be provided as a model for future research which will try to develop instruments for assessing attitude or knowledge of any new areas with constructs.

  • The purpose of this study is to provide a standard job description for a nutrition teacher placed in primary and secondary schools by analyzing their duties. DACUM is an acronym for 'Developing A CUrriculuM'. It was used by experts to determine the job duties, tasks and task elements to establish the job descriptions of a nutrition teachers through the development of a DACUM chart. An expert panel consisting of 10 nutrition teachers participated in a DACUM workshop and derived nutrition teacher's DACUM chart. A total of 1,550 nutrition teachers across the country were targeted as the survey subjects for validation of the DACUM chart through their perception of the frequency, importance, and difficulty of each item in the job description. A tree structure, criticality analysis, and contents validity index were added for verification. The definition of the nutrition teacher's job and DACUM chart with 5 duties, 28 tasks, and 107 task elements were derived by the DACUM method. The definition of a nutrition teacher was 'A teacher who is responsible for food service management and nutrition education and counseling for health promotion and disease prevention for students in primary and secondary schools'. The validation results of the tree structure were the priorities of the 28 tasks with ranks 1 and 2. Because there was no third priority, it was considered to be a good representation of the tasks of nutrition teachers. The DACUM chart was found to be evenly distributed with relative importances of more than 17 or less than 11 through the criticality analysis. Since the C5-4 (Conduct simulation exercise against food poisoning)'s content validity index was significantly less than the reference value of 0.78, it was not included in the final job description. 5 duties, 28 tasks, 102 task elements were included in the final job description of a nutrition teacher.

  • The current medical payment Insurance Rates in Korea stipulate charges for medical treatment by the doctor, pharmaceutist, medical technician and maternity nurse. But unfortunately didn't specify those charges for nursing done by the professional nurse. Only basic nursing fee is accounted insufficiently in current medical insurance fee schedule. therefore, Being face with covering entire people by medical insurance by 1991, It seems that the problems pertaining to operating the hospital and medical insurance system would be incessantly expanded in that no mention is made of medical charges rendered by major medical producer service in the current system, For that reason, this study made an attempt to clarify the importance the professional nursing puts of the current medical payment. The purpose of this study was to accounting nursing fee which diveded into the current medical fee schedule. (Method) 1. Data collection; Importance and difficulties in nursing activities was conducted in 'S' National University Hospital. Total nursing activities were selected 72 items which included direct care and indirect care. This study was conducted to evaluating the degree of importance and difficulties according to nursing activities through questionnaire to 204 RN. and so relative difficulties (acuity) were computered because the nursing cost level of each nursing service was differently established by the equivalent coefficient according to degree of relative difficulty and time required. 2. Calculation of cost according to nursing activities; After 47 nursing activities were selected in General surgery nursing units, calculation of nursing cost was as follows Cost of Nursing activity = (relative difficulty X Average hourly wage and benefits of nurse) + material cost of nursing -t- Average nursing administration cost So, Calculated cost by nursing activities was compared to current non-insured and insurance rate. 3. Calculation of nursing cost by K - DRG ; Total of 578 patients who were hospitalized in General Surgery units from January to March 1988 ware classified by K - DRG After estimation of total nursing cost based on the K-DRG, verified the appropriateness of basic nursing fee in medical insurance rate (Results) 1. Analysis of degree of importance and difficulties were 4.16 and 3.67 based on 5 point scale. This score were judged that it is worthy specifying the nursing fee 2. The nursing cost of 47 nursing service items in general surgery patients showed that the average cost of nursing activity was \1374.5 and The lowest cost was \217 of 'oral administration nursing' item, The highest cost was \11,025 of 'saline enematill clear' item 3. The result of comparison between the calculated cost by nursing activities against the current non-insured and insurance rate showed that 13 items(27.7%) involved to payment of insurance rate, 9 items(19.1%) involved to non-insured rate, remainder 25 items (53.2%) were not charged anywhere of total 47 nursing activities 4. When calculated cost by nursing activities was 100. current insurance rate was 62.3, non-insured rate was 176.6. Therefore this showed that most of non-insured rate were higher than calculated nursing cost. The insurance rate, however, were lower than it. Reim-bursement was imputed to non-insured patients. So the current rate system became estrainged from cost system. When Remainder 25 items of nursing activities compared' to \1390 of daily basic nursing fee per patient belonged to payment as a insurance fee schedule, basic nursing fee schedule was 1-2% of calculated cost of nursing activities. Therefore it showed that nursing fee was not counted adequately in it. 5. Nursing cost by K-DRG estimated in chart review based on counting number of nursing activities and length of stay The result showed that average amount of total nursing cost was \183828.1 Comparison of nursing cost calculated by K- DRG and basic nursing fee schedule showed that only 12.3% of nursing cost was charged (Conclusion) From the above research result, It is fact that nursing prime cost should be estimated more accurately and included adequately in current medical payment system. The payment system of nursing activities should be introduced not only nursing activities of drug administration and injection fee belonged to insurance fee schedule but also most nursing activities belonged not to mekical fee schedule. Even if introducing payment system of nursing activities, It should be estimated scientific method of Accounting nursing cost So nurses could offer nursing care of good quality, thereby they could make a great contribution not merely to the convalescence of the patient but to the promotion of the people's health.

  • 국내 신축 공동주택 건설은 2002년 11% 이상의 증가를 기록한 후 매년 3~4% 대의 꾸준한 증가추세를 보이고 있다. 최근 공공부문의 아파트 신축공사 현장에서 폐기물 분리발주제도에 의한 최초 발주물량과 실제 발생물량의 과다한 차이가 발주자와 수급인 사이에서 빈번하게 논란을 일으키고 있다. 이에 대해서는 현장 환경관리 미흡, 초기 계약물량의 과소 등 다양한 원인이 제기되고 있으며, 특히 건설폐기물 수량 예측에 적용되는 발생원단위 기준에 대한 개정 요구가 갈수록 증가하고 있다. 대부분의 현행 원단위는 2000년대 초에 수립되어 기술 발전에 따라 새롭게 적용되는 자재와 공법으로 인한 폐기물 발생 유형과 수량의 변화를 반영하지 못한다는 문제점을 지니고 있다. 따라서 본 연구는 보다 정밀한 신축아파트 폐기물 발생 원단위를 개발하기 위한 기초작업으로서 현장의 공종별 폐기물 발생 유형과 수량 예측방법을 명확히 하고자 하였다. 이를 위해 2010년에서 2013년 사이에 착공한 신축 아파트 10개 현장의 건축공사 내역서를 확보하고, 건설폐기물 전문가와 현장 폐기물관리 담당자의 의견을 반영하여 각 내역항목에서 발생가능한 폐기물 유형과 실질 할증률을 검토하였다. 본 연구에서 가설공사부터 지급자재부문까지의 건축공사 내역항목별로 정리한 폐기물 발생여부와 유형, 수량예측 시 반영여부, 손실률 등의 자료는 향후 보다 현실적인 데이터에 근거한 간접추계방식의 원단위 개발에 기여할 것이다.
